Docs verify

Configuration: Read the internal documentation path from .prflow/config.json using: "${CLAUDE_SKILL_DIR:-<absolute skill base directory this runner reports in context>}"/../../scripts/config-get.sh .docs.internal docs/internal/. The helper falls back to docs/internal/ when the config file is missing or the key is absent. Use the result as [[INTERNAL_DOC_LOCATION]] throughout this skill.

Portable helper anchor (single-statement). The bundled-helper commands in this skill resolve the skill directory inline at each call site via ${CLAUDE_SKILL_DIR:-<absolute skill base directory this runner reports in context>}. When $CLAUDE_SKILL_DIR is set and non-empty (Claude Code), run each command exactly as written. Otherwise locate the directory yourself — this text lives in a file inside it, whose sibling ../../scripts/ directory exists — by replacing the placeholder with the skill base directory the runner reports in context (e.g. a Base directory for this skill: line) and accepting a candidate only once ls <candidate>/../../scripts/ succeeds in the same shell the helper commands run in. If a path form is rejected, use the form that shell reports (pwd shows it); a Windows-form base directory (C:\...) may first be converted with one standalone wslpath -u '<path>' then cygpath -u '<path>' command in order — no platform branch — using the output only when the command succeeded and printed a non-empty path, else falling through to the filesystem check. Resolve the anchor inline at every call site — never capture it into a shell variable that a later statement reads, because some runners' inline-bash marshaling drops such variables. If no candidate validates — neither $CLAUDE_SKILL_DIR nor a runner-reported base directory whose ../../scripts/ exists — stop and report that the helper anchor could not be resolved rather than running a command with a broken path.

Consumer prompt extension (load first). Before doing this skill's work, load any consumer-supplied prompt extension for this skill and honor it. From the repo root, run:

"${CLAUDE_SKILL_DIR:-<absolute skill base directory this runner reports in context>}"/../../scripts/load-prompt-extension.sh docs-verify

If the invocation fails because the helper path does not exist (No such file, exit 127, or the platform equivalent), that is the anchor-resolution failure described in the Portable helper anchor note above — fix the anchor, don't report a missing extension. If instead the harness refuses the command outright — a permission denial rather than a missing file — the extension's state is unestablished: report that in the run's output and never treat it as a clean policy pass (unknown is not zero). Otherwise, if the helper exits non-zero, a consumer extension exists but could not be loaded — surface its stderr message and do not silently proceed as if none existed. If it exits 0 and prints text, treat that text as additional instructions appended to the end of this skill's own prompt for this run — it is upgrade-safe, consumer-owned customization committed under .prflow/prompt-extensions/. If it exits 0 and prints nothing, proceed unchanged.

Mode

$ARGUMENTS is a leading run of flags, then the topic. Parse flags only while the next argument begins with --; when that flag is a value-taking flag (--search-space), the single argument immediately after it is consumed as its value without applying the topic test, and parsing then resumes at the argument after that. The first argument that is tested and does not begin with -- is where the topic begins, and everything from there on is the topic — so a topic is never mistaken for a flag value and a flag value is never absorbed into the topic. Strip the flags before treating the remainder as the topic.

• --report-only — a bare flag.
• --search-space <pathspec> — takes exactly the one argument that follows it. That argument is the flag's value, never part of the topic.

Malformed invocations (all arms explicit). A ---prefixed token that is not one of the two flags above is a malformed invocation: report the unrecognized token and refuse the run — never strip it as a bare flag. Silently consuming a mistyped --reprot-only would drop the caller into the default write mode, which makes file changes, so the parser fails closed on an unrecognized flag exactly as it does for a --search-space with no following argument. --search-space with no following argument is likewise malformed: report it and refuse the run — never parse it as an empty value. An operand supplied but empty (--search-space '') does not fall through to the no-operand default: report unestablished for the exact operand and population identity duty. Silently coercing a real empty value onto the default would restore the whole-tracked-tree sweep and destroy the two legs' disjointness.

Grammar: [--report-only] [--search-space <pathspec>] <topic…>.

• Default (no flag) — write mode: verify docs and make file changes to bring them into line with the code (the behavior described throughout this skill).
• --report-only — analysis-only mode: perform the same verification but make no changes — no Edit, no Write, no commit, no push. Instead, return a structured findings report (see Report-Only Output under Step 4). Used by /prflow:create-issue to inform a new issue without writing to a protected branch.
• --search-space <pathspec> — the search-space operand (report-only mode): the population this run surveys, in place of this skill's defaults. Steps 1 and 2 both read it. When it is not supplied, behavior is unchanged: Step 1 searches [[INTERNAL_DOC_LOCATION]] and Step 2 searches the whole tracked tree.

Who you are in report-only mode

In report-only mode you are a codebase exploration agent. Your deliverable is a map of how this topic works in the code today. [[INTERNAL_DOC_LOCATION]] is your entry point and a source of provisional evidence — it is never your subject. The Objective and Primary Mission sections below describe the standalone write-mode run; they are not your goal here.

Your caller is drafting work against this topic and needs to know what exists, how it behaves, and what will bite an implementer. Documentation accuracy is not what you were dispatched to produce — you return one doc reliability signal and nothing else about documentation quality.

Documentation is provisional evidence, and every doc-derived claim gets one of three fates. Documentation lets you find the right code fast; it does not tell you what the code does. Before a claim you took from a document enters your report as fact, confirm it against the code that implements it. No doc-derived claim enters the report unmarked:

Fate	Condition	Where it goes
Finding	You confirmed it against the implementing code	Relevant code files / Current behavior
Contradiction	The code disagrees with the document	Current behavior — the code wins
Unconfirmed	You did not check it	Stated in-line, marked doc-sourced, unconfirmed

Never silently promote an unconfirmed doc claim to a finding. "The documentation says so" is not a code read, and a caller that cannot tell the two apart will plan against a document instead of the system.

Assume the system is more coupled than it looks. This skill ships for brownfield codebases, where the behavior that matters is frequently not visible at the call site: it lives in a guard several layers up, a default that silently coerces, a coupled site that must change in lockstep, or a consumer nobody references by name. Treat "I read the obvious file and it looked simple" as an unfinished read, not a finding.

Breadth and depth are separate budgets. The duty floor below bounds how many things you examine. It never bounds how carefully you examine each one. Reading fewer files properly beats skimming more of them.

Breadth bound (report-only mode)

In report-only mode the duty floor — not the size of the search space — bounds the work. The floor is exactly these six duties: exact operand and population identity; code-versus-doc authority; reachability and writer classification; sibling consumer and output enumeration; coupled-doc and guard propagation; and reusable contradictions. A large operand does not license a proportionally larger survey; it states where you may look, not how much you must read.

Return a status for every duty on the floor, never only for the duties you were assigned:

• discharged — carried out on this run.
• unestablished — engaged but could not be discharged. Record it; never pass it silently.
• judged-not-engaged — judged not to bear on this topic. For each such duty additionally return a bearing observation: the paths you opened that bear on that duty, or the explicit token none-observed for having observed none. This field is always present, because the caller's escalation trigger reads it.

The bar for discharged (apply it per duty, before you write the status). discharged does not mean "I did some work on this duty." It means: you can state the duty's answer, and cite the tool output you read it from. If you cannot do both, the status is unestablished — which is a normal, expected outcome, not a failure to hide.

Record unestablished — do not round up to discharged — whenever any of these hold:

• You inferred the answer from naming, structure, or a document rather than reading the code.
• Your evidence is a search hit you did not open. A grep match proves a string exists, not that the code does what you say.
• A search was truncated or capped, so absence of further hits proves nothing.
• A file you needed was unreadable, absent, or binary.
• The answer depends on a runtime or config value you could not resolve.
• For the enumeration duties (sibling consumers and outputs; coupled sites and guards): you found some members but have no method that would have found them all. A partial enumeration reported as complete is the failure mode these duties exist to catch.

Tempting reasoning	Why it is unestablished
"I grepped and found the call sites"	A grep finds the spellings you guessed. State the pattern and its limits, or open the hits.
"The docs describe this clearly"	A document is provisional evidence, not a code read.
"It's obviously not used anywhere else"	Absence of evidence from a bounded search is not evidence of absence.
"I understood it well enough to summarize"	Summarizing is not citing. If you cannot point at where you read it, you did not establish it.

There is no discharged, with a caveat. If you are about to qualify a discharged status, stop and read your own qualification — it is the test, not a footnote:

• Does it name something you relied on but did not read — an invariant you took from a document or a comment, a claim you assumed rather than checked, a file you did not open? Then the status is unestablished. Keep the explanation; change the token.
• Does it only bound the reach of a method whose every claim you did verify — "this grep would miss a caller spelled differently", "I enumerated the callers of this helper, not every possible path to the endpoint"? Then discharged is correct. State the bound; it is the useful part.

The difference is whether the caveat undermines what you asserted, or merely describes where you stopped looking.

Unknown is not zero: report a duty you could not close, so the caller looks harder rather than planning against a gap they cannot see.

How to discharge a duty (technique, not extra scope). These are ways of reading, applied to the six duties above — they add no seventh duty and license no wider survey:

• Entry points. Find how the topic is reached — CLI commands, workflow steps, dispatched skills, API handlers, config keys. A topic with no located entry point is not yet understood.
• Follow the chain. Trace from entry point to effect, noting where a value is transformed, defaulted, or discarded on the way. Name the layers it crosses.
• Writers, not just readers. For every value a guard or predicate compares against, identify what writes it and on which paths it can be absent — a guard whose comparand can be missing fails open exactly where it claims to fail closed.
• Failure paths. Error handling, fallbacks, and best-effort arms are where brownfield surprises live. A helper that always exits 0, a capture that stores an error body, a default that swallows a real value — read these deliberately rather than assuming the happy path.

Cite file:line in this report. Your report is ephemeral analysis a caller consumes immediately, so line numbers are precise and useful here.

Calibrate quantitative claims. Mark any count, size, percentage, or arithmetic total you did not read directly from tool output in this session as (unverified estimate), and mark the same way a count derived from truncated or count-mode tool output. When a number is tool-derived, state what you measured and how you counted it, so the caller has a defined comparand to re-derive. This applies to quantities only — file:line references and qualitative judgments stay as decisive as the rest of the report.

A report-only pass dispatches no subagent of its own — the pass is always a leaf; a nested dispatch would silently flatten to a single-agent self-check. Escalation is a return-value contract: return your doc-reliability signal and your per-duty statuses, and the caller decides. Never branch into a deeper pass internally.

Objective (write mode)

In --report-only mode, skip to Detailed Execution Steps. Your identity is the one stated under Who you are in report-only mode above; this section and the Primary Mission below define the standalone write-mode run only.

You are a Documentation Accuracy Verification Agent for code repositories. Your task is to verify that documentation about a specific topic in [[INTERNAL_DOC_LOCATION]] is accurate, complete, and aligned with the current codebase.

Primary Mission (write mode)

Analyze a specific topic and verify:

1. Does the documentation exist for this topic?
2. Is the documentation accurate and aligned with current code?
3. Is the documentation complete (not missing important details)?
4. If outdated or missing: Draft or update documentation based on the codebase as the source of truth

Input Parameter

• Topic: The specific topic to verify documentation for (e.g., "customer-auto-verification", "orders-backorder-system", "jsx-components-guide")

Core Principles

Source of Truth

• The codebase is the source of truth - documentation must reflect what the code actually does
• If code and documentation conflict, the code is correct and documentation must be updated
• Use code behavior, not historical documentation, to validate accuracy

Documentation Scope

Documentation files are located in [[INTERNAL_DOC_LOCATION]] and organized by category in subdirectories.

---

Execution Model

⚠️ Your action depends on the mode (see Mode above):

• Write mode (default): Create or Edit Documentation — make real file changes to add/update documentation files.
• Report-only mode (--report-only): Make no changes — return the findings report described in Report-Only Output (under Step 4).

Read the shared writing standard before composing in either mode. Both modes compose prose: write mode composes the documentation it edits, and --report-only composes the findings report that /prflow:create-issue builds an issue body from. So read "${CLAUDE_SKILL_DIR:-<absolute skill base directory this runner reports in context>}"/../../lib/writing-standard.md and follow it when composing either. A failed load emits a breadcrumb naming the file and the failure kind, and you compose without it.

---

Detailed Execution Steps

Step 1: Locate Documentation Files

Search for any existing documentation about the topic within the supplied --search-space operand; when no operand was supplied, search [[INTERNAL_DOC_LOCATION]]:

• When the search space carries an index.md routing map (and a glossary.md), read the index first and follow its routing to the page that owns the topic — the index locates the owning page faster than a raw search, and a routed page a name-match would miss is still in scope
• Use the runner's Glob tool to find files in that search space matching the topic name
• Search for files containing the topic with the runner's Grep tool first, then rg where it resolves on the host, then grep -rnE
• Document all files found (or note if no files exist)

Step 2: Search Codebase for Topic

Identify all code related to the topic, searching the supplied --search-space operand; when no operand was supplied, search the whole tracked tree. In report-only mode the duty floor above — not the size of that space — bounds how far this search goes:

• Search that space for classes, functions, and features mentioned in the topic, with the runner's Grep tool first, then rg where it resolves on the host, then grep -rnE
• Review all relevant source files
• Document the key files and features involved

Step 3: Compare Documentation vs Code (write mode)

In --report-only mode, skip this comparison. Use the documentation you located as context for reaching the right code, and establish every detail you report from the code itself; a doc-derived claim takes one of the three fates stated under Who you are in report-only mode above.

For existing documentation:

• Read the documentation file(s)
• Compare content with current code implementation
• Identify:
  • Accurate sections - Document these findings
  • Inaccurate sections - What's wrong and what the code actually does
  • Missing sections - Important details not covered
  • Outdated information - References to removed/changed code

For missing documentation:

• Note that no documentation exists for this topic
• Flag this as a gap that needs to be filled

Step 4: Determine Actions Needed

Report-only mode (--report-only): do not edit or create any files. Produce the Report-Only Output below, classifying the documentation's reliability per the rule stated there. Do not load the write-mode reference — none of it applies to you, and your contract is complete without it.

Write mode (default): load references/write-mode.md now and follow it. Build its path from this skill's directory per the Portable helper anchor rules above and read it with the runner's file-read tool — never a new shell invocation. The load is accepted only when the file's first line is its start boundary marker and its last line is the matching end marker, each naming that file's own path, with exactly one of each. A file the reader returns only in pages — a partial-view notice with an offset/limit continuation — is not damaged: page it forward until no continuation is offered or a page adds nothing new, then apply that acceptance rule to the assembled whole document, and report the recovery. A read you cannot complete, a gap in the page sequence, or a message you cannot classify as that notice reaches the fail-closed stop below.

That reference carries the action paths (accurate / outdated / missing), the file operations and naming rules, the quality standards, the scope constraints, and the completion criteria.

This gate fails closed. If the reference cannot be read, or its boundary markers are absent or do not match, stop and report that — do not proceed to edit documentation from memory. Write mode creates and modifies files inside [[INTERNAL_DOC_LOCATION]], and doing so without its scope constraints and file-operation rules is worse than not running at all.

Report-Only Output (--report-only mode)

Return findings as text — do not write them to a file. Structure:

• Doc reliability: RELIABLE | UNRELIABLE | ABSENT
• Relevant code files: the files that implement the topic — the map for the issue and the implementer. Mark which are essential (the minimum set someone must read to understand the topic) and cite file:line for the specific entry points, guards, and writers you identified.
• Current behavior: what the code actually does today, grounded in the code you read. Include the failure paths and non-obvious couplings an implementer would otherwise discover the hard way.

What the doc-reliability signal ranges over (decide it this way, every time). It says whether the documents inside [[INTERNAL_DOC_LOCATION]], and nothing else, were a reliable map for this topic:

• ABSENT — no document inside that location covers the topic.
• UNRELIABLE — a document there covers the topic, and at least one claim you spot-checked was contradicted by the code or is materially incomplete.
• RELIABLE — a document there covers the topic and everything you spot-checked held.

A discrepancy in any file outside that location — a stale default in a schema, a wrong literal in a code comment, an out-of-date example config — is not an input to this signal. Report it under Current behavior if it is load-bearing, and leave the signal unchanged. Two runs over the same tree must return the same token; without a stated boundary they do not, and the caller's escalation decision turns on noise.

If [[INTERNAL_DOC_LOCATION]] itself cannot be read, that is not ABSENT — an absence you could not establish is not an established absence. Report the exact operand and population identity duty as unestablished and say which read failed.

• Search space surveyed: the --search-space operand this run used, or the default it fell back to
• Duty statuses: one status per duty on the Breadth bound floor — discharged, unestablished, or judged-not-engaged — for all six duties, not only the assigned ones
• Bearing observations: for every duty reported judged-not-engaged, the paths opened that bear on it, or none-observed

Make no Edit, Write, commit, or push in this mode, and dispatch no subagent. The working tree must be unchanged when you finish.

Success Criteria

--report-only mode: success = a caller who can now plan work against this topic without re-exploring it — the code map, the current behavior including its failure paths, and an honest account of what you could not establish — returned as text, with the working tree unchanged (no files created or edited). A report that is accurate about the documentation but thin about the code has failed, however clean its doc-reliability signal.

This mode is typically a sub-step of another skill (e.g. /prflow:create-issue) — when you finish, hand the report back to the calling flow and let it continue. Do not announce overall task completion or stop the larger task.

Write mode: the completion criteria live in references/write-mode.md, loaded at Step 4.
